Wash. Rev. Code § 70.42.170
The department may at any time conduct an on-site review of a licensee or applicant in order to determine compliance with this chapter. When the department has reason to believe a waivered site is conducting tests requiring a license, the department may conduct an on-site review of the waivered site in order to determine compliance. The department may also examine and audit records necessary to determine compliance with this chapter. The right to conduct an on-site review and audit and examination of records shall extend to any premises and records of persons whom the department has reason to believe are opening, owning, conducting, maintaining, managing, or otherwise operating a test site without a license.
Following an on-site review, the department shall give written notice of any violation of this chapter or the rules adopted under this chapter. The notice shall describe the reasons for noncompliance and inform the licensee or applicant or test site operator that it shall comply within a specified reasonable time. If the licensee or applicant or test site operator fails to comply, the department may take disciplinary action under RCW 70.42.120 through 70.42.150, or further action as authorized by this chapter.
